Back in 1999 you couldn't go to a club without hearing the Funkstar De Luxe take on Bob Marley's Sun is Shining. There were a number of remixes and I have a few of them on two Funkstar releases.

But for the life of me, I still can't find one particular one I remember hearing.

Take a listen to this ATB Airplay Mix

Can anyone identify where the guitar bit at the beginning comes from (other song)?

I remember a mix playing here in the Toronto area where the rif was much more prominent than the mix I just linked above. I've already checked the ATB Club Mix and it's not the one I'm looking for either.
